[osg-users] Visualizing triangle data

[Robert Osfield]

HI Sam,

Have a look at the osggeometry example as this illustrates how to set up
geometry data, which includes triangles.  For the traingle mesh what you'll
likely want to do is use an osg::DrawElementUShort(GL_TRIANGLES) and then
add you triangle indices to this.

Robert.
